tov letters and figures of referenceindicnte corre sponding parts. 7 I Thisinveut ion relates to improvements in envelop-fasteners, the object thereof being to.

provide a means for"fast"ening envelope or r other similar packages in such a, secure unanherjas to prevent opening thereof without de-' straying the envelop, whereby surreptitious opening {111(1 "reolos'ing' of envelope While in transit is pre vented.

The invention will hehereinsfter fully described, and specifically set for-thin the en'- n'exed claims.

In the accompanyingdrawings forming part of this specifioation Figure 1 isaperspeotive viewof my improved fastener, shows ing the seme'inopen position. Fig. 2 is it perspeotive viewillustrating the device attached to an envelop closed and sealed, and, Fig. 3-

is 'a. side-elevation illustrating a slight struc- 30. tursl modification. In the-practice'of my invention I employ an upper plate A and s loi'ver plate B.-'- T plates are composed of resilient sheet metal, and they are preferahlymsde integralwith v I bent upon a transverse line through the center, 05 the'plete. Upon the :upper surface of-th'elower pinto B, I place s sheot'of'fnbric C and fasten the same to the I said plsteby means of points or spursln which 40 are stamped fl'OII} the said plate and form an integral pert thereof. The upper plate A is provided at the center thereof with a'series of angularlyextended pointed tongues a;

' which areistamped mm the surface of the '5 said plate and bent at an angle outwardly; The outer edge of the said plate A is also provided with any suitable .ed tongues a. These tongues form an into- I 'g'ral part oftheplatc and -they, are bent at an an lo irwirardlya v 5111 t oio eration'and use of the invention the piste. is plfiod'uponthe inside of the Sonno'rinnn,

the material composing the envelop and 51150 through the fabric 0,

'pliedwith pointed 'gle' piece of sheet numberof pointor slit 1, formed through the back of the en'- velop. Having placed the plate imposition, the upper plate B is bent over uponthe'oute'r surface of the envelop and given a sharp blow with a flat instrument, which causes'the angular points formed thereon to pass throi gh v v interposedb'etween the two said plates, and by contact with the lower plate these said pointsare bent and clenched, thus retaining the envelop in a securely-fast? toned condi ion, and th fabric sheet prevents accidental tenringof the paper on velop while the same is in transit. Y j

In. the modification illustrated by'F'ifg. 3 of the drawings 1 use an-upper plate D, of any suitable contour, and a lower. plateE of cor' responding shape. vThe upper plate is sup? tongues d and d,,-a.nd'the' lower plate is. provided withafabric sheet Ff, which is secured by means of thebent Having thus described my invention, what I claim as new, and desire tosecure hyaLetters' Patent, is-- v 1'. An envelop-Iastenen comprising an upper plate having a. series of centrally-located pointed tongues extended from th'eunder surface thereof at an angle outwardlygnnd a so ries of pointed tongues-extended from the edge thereof at an angle-inwardly; in combination wither lower plate havingnoproject- 'ing tongues or spur-sand having its faceopposits the tongued face of the upper plate covered with a fabric secured thereto and int'o' which fabricthe tongues of-Y the upper pinto bind when clenched; substantially as shown and described. p

2. In an envelop-fastener, the combination of an upper and a lower plate. formed of a sinmetal and bent into shape relative toeach other, a sheet of fabric secured to and covering' tho'upper surface of thelowr plate,snd a series often use formed integral with the upper plate. an extending centrally-therefrom at an angle outwardly, and adapted for. beingbcntnpon-tho upper surface of the lower late, by contact there-w with, and a series of pointed tongues extended irorn the edge of the; said upper plate at an angle inwardly, said tongues of thenpper sealed envelopQand it ezitends through a slot plate entering and binding under the fabric. ing the envelop for the purpose of fastenin face of the lower plate when the same are the same and bind under the fabric face of i5 clenched, substantially as shown and-'dethe lower plate when they are clenched, subscribed. sLant-ially as shown and described.
